6 Conclusion

The ultimate choice of a power topology boils down to the intended use case of that specific EV Charger namely the targeted power levels, efficiency & power density targets to name a few. While high power highway chargers (or fleet chargers) would look at complex multilevel three-phase PFC and DC-DC stage to pack more-and-more power into them, the new emerging portable chargers could be addressed by a simple interleaved totem pole PFC stage followed by a LLC DC/DC stage. With interest in new requirements like V2G, engineers may have to limit their topology choices to those that support bi-directional power transfer between the Vehicle and the Grid.

No matter, your choice of use case the advancement in the field of power electronics in tandem with semiconductor technology is ready to offer everything you need to build your next generation DC Fast EV Charging Station.
